IPC: G01G17/00
Filed: 1993-11-05
Abstract: PURPOSE:To accurately measure powder at once at a high speed by electrostatically eliminating a charged photosensor in which the powder is attracted and taking out the powder. CONSTITUTION:An OPC photosensor 1 is excited by a light of a light source 3 passed through a slit of a variable width slit plate 3 while rotating by a drum rotating unit 10 and charged with static electricity.

When the drum 1 is rotated, the powder 4 on the surface of the tank 7 is pulled by electrostatic attraction force of the drum 1, and adhered to the surface of the drum 1. The adhered powder 4 is made uniform in thickness in a squeegee plate 6, and excess powder 4 is scraped OFF and returned to the tank 7. The drum 1 in which the powder 4 remains adhered is moved on a recovery tank 9 at the stage 8, and the surface of the drum 1 is electrostatically eliminated while rotating the drum 1. The powder 4 is dropped since its attraction force is eliminated, recovered in the tank 9 and metered.

Title: Method for waveform analysis
Inventor: KAKISHITA MASAHIRO
IPC: G10L25/27
Filed: 1999-09-29
Abstract: PROBLEM TO BE SOLVED: To provide a method for waveform analysis which analyzes useful frequency components of an original waveform with a high precision. SOLUTION: This method for waveform analysis is used as a tool to generate a waveform by waveform composition. In a step S33, waveform data having the one-frame length are successively segmented from original waveform data WAVE so that one-frame periods may overlap, and they are subjected to FFT (fast Fourier transform) analysis processing to detect frequencies, amplitudes, and phases of frequency components. Plural frequency components the amplitudes (peak amplitudes) of which are larger than those of preceding and succeeding frequency components are outputted as trace data DD(i). Remainder waveform data RW(i) obtained by subtracting a waveform SW(i) composed of trace data DD(i) from an analysis object waveform IW(i) are taken as a new analysis object waveform IW(i) to perform FFT analysis again.

Title: Surface coating agent
Inventor: SHIDA MEGUMI
IPC: B41M7/02
Filed: 1986-11-21
Abstract: PURPOSE:To enable high-speed printing and enhance printing efficiency and printing quality, by composing a coating agent for a printing ink of a sodium salt of carboxylmethyl cellulose, an alcohol, an ester, a preservative, a fluoro- surfactant and water. CONSTITUTION:The amount of a sodium salt of carboxylmethyl cellulose added is set to be 3-10pts.wt., whereby the viscosity of a coating agent can be made to be 1-10P. If the viscosity is less than 1P, the viscosity is so low that the thickness of a coated film is small, whereas if the viscosity is more than 10P, it is necessary to prepare a diluted coating solution from the viewpoint of operability in coating. In both cases, a sufficient offset-preventing effect can not be displayed. The amount of an alcohol added is 3-10pts.wt., whereby wettability of an ink and the coating agent is enhanced. The amount of an ester added is 3-10pts.wt., whereby formation of a film of the coating agent on the ink is facilitated. The amount of a preservative added is 0.001-0.1pt.wt., and the amount of a fluoro-surfactant added is 0.01-1.0pt.wt.
